Specification of Letters Patent.

Patented July 26, 19M

Application filed May 26, 1906. Serial No. 318,877.

To all whom it may concern:

. Be it known that we, 'lanononn Cnnrsrnw FRYE and CARL EDWARD lllAGNUSSOIY, citizens of the United States, and both residing at University Station, in the city of Seattle, in the county of King, in the State of Wash: ington, United States of America, ha e invented or discovered new and useful lron esses of Preparing seaweeds for food.

Our invention consists of processes by which useful and palatable food products are obtained by eliminating the unsavory and nauseating taste of the stalks and bulbs of the plants, 1V ercocg sfiz's and 1 Waoophycus, species of the marine rllgu, by chemical and physical processes and by the addition of certain ingredients.

The stalks and bulbs of the plants, Ne-

rcocg/stz's and Pclagoplzz mm, are cut into any desired form, either directly or atter first paring. These plants 1n their natural state have an unsavory and nauseating taste,

which unfits them for use a food; it, however, the stalks and bulbs are subjected to the action of acetic acid (C ILO or solutrons whose actli principle 1s acetic acid,

7 onto the action of any of the oxidizing agents, bleaching powder, chlorin gas or hydrogen peroxid (H 0 then the unsa'-.

vory and nauseating taste is destroyed and a valuable food product is produced.

In using acetic acid the stalks and bulbs of the plants, Nci cocystis and Pelagophycus are placed in a closed vessel. and covered with a dilute solution (about 4 per cent.) of acetic acid; the mixture is then heated and kept at boiling point for about fifteen minutes; the weaker the acid the longer it needs to be boiled and the tougher the resulting product. The acetic acid is then removed from the treated stalks and bulbs by soaking in water; where acetic acid has been used heretofore in the preparation of food it has remained with the food and is eaten with it, and the foods were edible and useful before treatment, but in this case the substance treated is non-edible and useless, but by'and through the process indicated and the removal of the acid the nauseating taste of the slllJStilIlt'L completely destroyed but Without decomposing the fiberor form of the plants, its color changed somewhat, and the resulting substance which is in form unchanged, is edible and useful and may be used in the making of a variety of other food products, such as preserves, jellies, marmalades, candied or sugared products by boiling in sugar and flavoring substances, and various kinds of pickles. It has been Found that the action of the acetic acid is facilitated by first boiling the cut stalks and bulbs,

Having thus described our invention or discovery, what we claim as new and useful and desire to secure by Letters Patent of the United States, is

l. The process of eliminating or destroy ing the objcctionable tastes in and belonging to the species of the marine Algaz, known as Ncicocystz's and Pclagoplz-ycus by exposing the same in a closed vessel to the action of dilute acetic acid (C l-L0 and heat for a definite time until the nauseating and unsavory taste is substantially removed, and subjecting the product to the action of water to remove the chemical.

' 2. The process of desavoring the plants of the marine Algae, known as Nereocystz's and Pelagophg cus by boiling the same in dilute acetic acid ((3 11 0 Washing the mixture to remove the acid, and then preserving the same by boiling in sugar and a flavoring substance;
